BLOWER COIL (2 THROUGH 10) UNIT CONTROL DIAGRAM
SEQUENCE OF OPERATIONS
CHILLED WATER SYSTEM CONTROL:
DURING THE OCCUPIED MODE, WHENEVER THE OUTSIDE AIR TEMPERATURE RISES TO THE SETPOINT OF THE DDC CONTROLLER, THE DDC CONTROLLER
SHALL ENABLE THE MAIN CHILLED WATER PUMP. ONCE FLOW HAS BEEN PROVEN THROUGH THE EVAPORATOR, THE DDC CONTROLLER SHALL ENABLE THE
CHILLER. ONCE THE CHILLER IS DISABLED, THE CHILLER WILL CONTINUE TO RUN THE CHILLED WATER PUMP UNTIL REFRIGERANT PRESSURES ARE IN THE
CHILLER'S LIMIT TO DISABLE FLOW.
THE DDC CONTROLLER SHALL MONITOR CHILLER CURRENT DRAW, EVAPORATOR TEMPERATURE AND CONDENSER TEMPERATURE ON THE CHILLER.
WHENEVER ANY OF THE ABOVE THREE VARIABLES REACHES SETPOINT, THE DDC CONTROLLER SHALL RESET THE LEAVING THE WATER SUPPLY SETPOINT
AND UNLOAD THE COMPRESSOR AND IF NECESSARY DE-ENERGIZE THE CHILLER. PID CONTROL SHALL BE UTILIZED FOR THE ABOVE SEQUENCE.
THE DDC CONTROLLER SHALL SELECT A DIFFERENT CHILLED WATER PUMP WEEKLY TO ACT AS THE MAIN, INDEXING THE OTHER PUMP AS A STANDBY.
WHENEVER THE DDC CONTROLLER SENSES THAT THE LEAD PRIMARY CHILLED WATER PUMP HAS LOST FLOW, THE DDC CONTROLLER, AFTER A TIME
DELAY (ADJUSTABLE), SHALL START THE STANDBY PUMP AMD DISABLE THE FAILED PUMP.
HOT WATER SYSTEM CONTROL:
ON A FALL IN OUTSIDE AIR TEMPERATURE TO THE SETPOINT OF THE DDC CONTROLLER OR WHENEVER HEAT IS REQUIRED, THE DDC CONTROLLER SHALLENERGIZE THE LEAD HOT WATER PUMP AND ENABLE BOILER
THE DDC CONTROLLER SHALL SELECT A DIFFERENT HOT WATER PUMP WEEKLY TO ACT AS THE LEAD, INDEXING THE OTHER PUMP AS A STANDBY.WHENEVER THE DDC CONTROLLER SENSES THAT THE MAIN HOT WATER PUMP HAS LOST FLOW, THE DDC CONTROLLER, AFTER A TIME DELAY(ADJUSTABLE), SHALL START THE STANDBY PUMP AND DISABLE THE LEAD HOT WATER PUMP.
BC-1 CONTROL:
THE DDC CONTROLLER SHALL ENERGIZE THE UNIT THROUGH ITS OPTIMIZATION PROGRAM FOR MORNING WARM-UP. DURING MORNING WARM-UP, THE
OUTSIDE AIR DAMPER SHALL REMAIN FULLY CLOSED, THE RETURN AIR DAMPER SHALL BE FULLY OPEN, AND THE HOT WATER VALVE SHALL BE FULLY OPEN
TO THE COIL.
AT OCCUPANCY TIME, THE DDC CONTROLLER SHALL OPEN THE MINIMUM OUTSIDE AIR DAMPER CLOSING THE RETURN AIR DAMPER A PROPORTIONAL
AMOUNT.
ON A RISE IN SPACE TEMPERATURE TO THE HEATING SETPOINT OF THE DDC CONTROLLER, THE DDC CONTROLLER SHALL MODULATE THE HOT WATER
REHEAT VALVE CLOSED TO THE COIL. ON A FURTHER RISE IN SPACE THE DDC CONTROLLER SHALL MODULATE THE OUTSIDE AIR DAMPER OPEN CLOSING
THE RETURN AIR DAMPER A PROPORTIONAL AMOUNT FOR FREE COOLING. WHENEVER THE SETTING OF THE MIXED AIR TEMPERATURE LOW LIMIT IS
REACHED, THE DDC CONTROLLER SHALL MODULATE THE OUTSIDE AIR DAMPER CLOSED TO ITS PRESET MINIMUM POSITION OPENING THE RETURN AIR
DAMPER A PROPORTIONAL AMOUNT. WHENEVER THE OUTSIDE AIR TEMPERATURE RISES ABOVE THE SETPOINT OF THE DDC CONTROLLER, THE DDC
CONTROLLER SHALL DISABLE THE ECONOMIZER CONTROL. ON A CONTINUED RISE IN SPACE TEMPERATURE, THE DDC CONTROLLER SHALL MODULATE THE
CHILLED WATER VALVE OPEN TO THE COIL.
WHENEVER THE SETTING OF THE FREEZESTAT IS REACHED, THE FREEZESTAT SHALL DE-ENERGIZE THE SUPPLY AIR FAN, CLOSE THE OUTSIDE AIR DAMPER,
AND OPEN THE HOT WATER AND CHILLED WATER VALVES.
ON DETECTION OF PRODUCTS OF COMBUSTION, THE SMOKE DETECTOR SHALL STOP THE UNIT SUPPLY AIR FAN AND CLOSE THE OUTSIDE AIR DAMPER.
DURING THE UNOCCUPIED MODE, THE BLOWER COIL UNIT UNIT SHALL BE CYCLED AT A REDUCED HEATING SETPOINT AND A RAISED COOLING SETPOINT.
(BC-2 THROUGH BC-10) BLOWER COIL UNIT CONTROL:
THE DDC CONTROLLER SHALL ENERGIZE THE UNIT THROUGH ITS OPTIMIZATION PROGRAM FOR MORNING WARM-UP. DURING MORNING WARM-UP, THE
OUTSIDE AIR DAMPER SHALL REMAIN FULLY CLOSED, THE RETURN AIR DAMPER SHALL BE FULLY OPEN, AND THE HOT WATER VALVE SHALL BE FULLY OPEN
TO THE COIL.
AT OCCUPANCY TIME, THE DDC CONTROLLER SHALL OPEN THE MINIMUM OUTSIDE AIR DAMPER CLOSING THE RETURN AIR DAMPER A PROPORTIONAL
AMOUNT.
ON A RISE IN SPACE TEMPERATURE TO THE HEATING SETPOINT OF THE DDC CONTROLLER, THE DDC CONTROLLER SHALL MODULATE THE HOT WATER VALVE
CLOSED TO THE COIL. ON A FURTHER RISE IN SPACE THE DDC CONTROLLER SHALL MODULATE THE CHILLED WATER VALVE OPEN TO THE COIL.
WHENEVER THE SETTING OF THE FREEZESTAT IS REACHED, THE FREEZESTAT SHALL DE-ENERGIZE THE SUPPLY AIR FAN, CLOSE THE OUTSIDE AIR DAMPER,
AND OPEN THE HOT WATER AND CHILLED WATER VALVES.
ON DETECTION OF PRODUCTS OF COMBUSTION, THE SMOKE DETECTOR SHALL STOP THE UNIT SUPPLY AIR FAN AND CLOSE THE OUTSIDE AIR DAMPER.
DURING THE UNOCCUPIED MODE, THE BLOWER COIL UNIT UNIT SHALL BE CYCLED AT A REDUCED HEATING SETPOINT AND A RAISED COOLING SETPOINT.
